Improvement of the piezoelectricity of PVDF-TrFE by carbon black

Materials Research Express, 2018
In order to prepare PVDF-TrFE films with high piezoelectric performance, carbon black (CB), in the range of 0.0 wt% to 0.8 wt%, was added into PVDF-TrFE/DMF solutions. To investigate the effects of CB on the power generation capability, various fabricated films were attached on a vibrating plate, and then the output voltages and harvested power density
